AFSK A not working, while DATA A is!?

[Frank R. Oppedijk-2]

Hi,

Most  of my operating time, I do CW, but sometimes I do some RTTY
QSOs. Today, after what must have been a couple of months, I felt an
urge to fire up MMTTY again, so I tweaked the necessary controls on
my K3 and on my PC soundcard. But no transmit output?! The PTT is
asserted and the receiver is muted, but no transmit output and no
monitor output. I rechecked all controls and referenced my notes, but
nothing wrong was found.

After experimenting a bit more, I found out that everything was
working fine when I changed the DATA MD from AFSK A to DATA A! Now
I'm puzzled: as far as I know, these two modes use exactly the same
inputs and controls...

Can anyone help me out? What setting or control can be the cause of this?

Thanks in advance,

Frank PA4N

Hi Frank.

Make sure the mark tone frequency your software is set up for matches  
the mark tone frequency the K3 is set for.  In AFSK-A mode, use the  
PITCH button (i.e. press and hold the SPOT button) to check and set  
the AFSK mark frequency.

See the section titled "Mark/Shift and Pitch Selection" on page 31 of  
the K3 Owners Manual.

AFSK A and DATA A both transmit the same on mine. Using HRD here.

I don't have the solution, but you are correct in that your K3 is not operating properly.

Hi Bob,

Thanks for your e-mail.

Kok Chen emailed me privately with the cause of the problem:

HI Frank,

 

I just love the K3 community. You can always find an answer.

 

That’s why mine is working, as the tone pairs match.

 

Now I have the challenge of getting this LP-Pan working.
